Garcia is the only one of the three callups with any major-league experience, having gone 2 for 12 in earlier stints with the Cardinals this season, but Pham has intriguing numbers, having hit .324 with 10 homers, 20 steals and an .886 OPS in 390 at-bats at Triple-A Memphis. Tuivailala, a converted infielder, has a 3.15 ERA, 1.25 WHIP and 14.6 strikeouts per nine innings in 48 appearances between three minor-league stops.
